Checking the Filter
The filters are among the most important items in the aquarium. As you know, it filters out the waste, thus trapping most of the waste and toxic materials. Mechanical filters need to be cleaned every 2-4 weeks; or more often if large debris become stuck. Never clean your filter too often. This will destroy the bacteria culture in the filter and prevent it from working properly. It is for the same reason important to never use hot water when cleaning your filter. Some bacteria must be allowed to survive in the filter and re-colonize it When the waste deposit near the filter becomes high, then filtration becomes-in effective. When using mechanical filters, you need to check whether the system is working properly every day to ensure water quality. If you discover the filter for some reason has been turned of you’ll need to clean it before turning it on again. This is due to the fact that the filter may contain toxic water after being turned of. The toxin is created when the oxygen is depleted when no new water is pumped into it.
If you start the filter without cleaning it, the toxin is released into the water and might harm or kill the fish in the aquarium.
